How are motors and magnets alike?

Magnets and electric motors are similar in that they both produce magnetic fields.


How do meters make use of magnetic fields?

Meters can make use of magnetic fields in devices like electromagnetic flow meters which measure the flow rate of a liquid by applying a magnetic field and detecting the resulting voltage induced when the liquid flows through it. Other meters, like magnetic field sensors, work by measuring changes in magnetic fields to sense the presence, position, or movement of objects or materials.


What tool does scientist use to find magnetic fields?

Scientists typically use a device called a magnetometer to measure magnetic fields. Magnetometers can detect and measure the strength and direction of magnetic fields in various locations. They are crucial tools in fields such as geophysics, astronomy, and materials science for studying magnetic phenomena.


What devices instrument that use electromagnets to operate?

Some devices that use electromagnets to operate include MRI machines, transformers, electric motors, and loudspeakers. Electromagnets are used in these devices to generate magnetic fields that can be controlled and manipulated to perform specific functions.


Do birds use magnetic fields?

no ...YES!


How is magnetic levitation used by magician?

Magicians use magnetic levitation in illusions by hiding strong magnets in objects or clothing to create the appearance of objects floating in the air. By controlling the magnetic fields, magicians can simulate the effect of levitation without any visible support. This technique adds mystery and wonder to their performances, creating a sense of magic.


Did the military use mine fields in the Korean war?

Yes mine fields where used but they were magnetic mine fields.


How you can stop or divert magnetic lines of force?

To stop or divert magnetic lines of force, you can use magnetic shields made of materials with high magnetic permeability such as iron or steel. These materials can redirect or absorb magnetic fields, preventing them from reaching a certain area. Alternatively, you can use electromagnetic coils to create opposing magnetic fields that cancel out or weaken the original magnetic field.


How to use the right hand rule in physics to determine the direction of magnetic fields?

To use the right hand rule in physics to determine the direction of magnetic fields, point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field.


Is it possible to use magnetic fields to prevent earth impacts by near earth objects?

This would not be a good way to go about it. Not all near Earth objects are metallic, they can be rocky or even contain volatile substances if they are cometary in origin. Even if they are made of nickel and iron, and are ferromagnetic, all a magnetic field can do is attract them, it cannot repel them. So, if you established your magnetic planetary protection device on the moon, and you had enough power to generate a sufficiently strong magnetic field, you could then attract near Earth objects to the moon rather than to the Earth. But there are simpler ways to deal with such objects.

How can you detect the presence of a magnetic field?

You can detect the presence of a magnetic field using a compass, which will align itself with the field lines. Other devices such as magnetometers can also detect and measure magnetic fields accurately. Additionally, certain materials, such as iron filings, can visualize magnetic field patterns when sprinkled around the area.
